I don't know who came up with COALESCE but IFNULL, which is 
functionally equivalent, always made more sense to me.

You probably have null fields rather than blanks. In oracle there is a 
funvtion called NVL, the DB2/400 equivalent is coalesce. You can either 
user coalesc in your emmbedded SQL select or use null indicators. I would 
suggest using coalesce as in

SELECT field1, field2, COALESCE(field3, '  '), field4
          FROM file1
This will put blanks in the field.
